I have suffered with seborrheic dermatitis for several years. It’s always worse in the autumn/winter although this year it flared up in the summer when it was very hot. I cannot get it under control on my face. It’s getting worse by the day. Can anyone recommend any treatments? I’m using nizarol shampoo on my scalp and also using it to wash my eyebrows - as the SD is particularly bad in that area. It’s growing on my eye lid though and I don’t know what to use on there. So fed up of it.
